Objective c UIWeb页面未加载

我正在尝试加载一个基本网页，但它没有加载。这有点奇怪

我有此代码（此代码无效）

但是如果我尝试

[itemSummary loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://westminsteriphone.wordpress.com/2011/08/23/another-blog-post/"]];

它起作用了这就是为什么第一个示例不加载

试试这个

 NSString *test = [item objectForKey:@"link"];
    NSLog(@" %@",test); // returns http://westminsteriphone.wordpress.com/2011/08/23/another-blog-post/
[itemSummary loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",text]]]]; 

[itemSummary loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",[item objectForKey:@"link"]]]]]; 

试试这个

 NSString *test = [item objectForKey:@"link"];
    NSLog(@" %@",test); // returns http://westminsteriphone.wordpress.com/2011/08/23/another-blog-post/
[itemSummary loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",text]]]]; 

[itemSummary loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",[item objectForKey:@"link"]]]]]; 

如果你在不同的函数中使用这两行，那么就这样做

 function 1

 NSString *test = [[NSString alloc]init];

 test =[NSString stringWithFormat:@"%@",[item objectForKey:@"link"]];


 return [test autorelease];



 function 2



 [itemSummary loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:test]]];

ddi您是否尝试使用loadRequest行上的breakbpoints进行调试？？如果没有，请检查测试在尝试加载请求时具有什么类型的值
